The invention discloses a pixel internal memory unit, a pixel array and a display device. The pixel internal memory unit comprises a first switch unit, a second switch unit, a third switch unit, a liquid crystal capacitor and an energy storage unit; a control end of the first switch unit is connected with a grid signal end, an input end is connected with a data signal end, and an output end is connected with a control end of the second switch unit, a control end of the third switch unit and a first end of an energy storage unit; the input end of the second switch unit is connected with a firstpower voltage end, the output ends of the second switch unit and the third switch unit are connected to the first end of the liquid crystal capacitor; the input end of the third switch unit, the second end of the liquid crystal capacitor and the second end of the energy storage unit are connected with the second power voltage end. Through the circuit structure corresponding to the pixel internalmemory unit with simple structure and less appliances and signals involved, the pixel internal memory unit realizes the low frequency display, saves cost, and reduces power consumption.
Description
technical field [0001] The present invention relates to the technical field of displays, in particular to a storage unit in a pixel, a pixel array and a display device. Background technique [0002] The smartwatch market has been booming since LG released its first smartwatch, the G WatchR. As a result, in recent years, not only international major manufacturers have made efforts in the field of smart watches, but Chinese manufacturers have also increased their market-related layout in this field. In terms of improvement in liquid crystal technology, Japanese panel manufacturers have introduced MIP (memory-in-pixel) technology into reflective LCD panels to reduce panel power consumption. In 2015, Japan Display announced the launch of an ultra-low power reflective LCD panel using MIP technology, which can be applied to wearable devices. The LCD panel can not only achieve 64-color display, but also has advantages in power consumption, which can be compared with Sharp LCD pan...
